A specialised parahydrogen rig, part of the gas handling kit, has been designed to be used mainly with TOSCA.

Parahydrogen is required to study the rotational line of molecular hydrogen. We produce parahydrogen by liquefying hydrogen at 20 K on a paramagnetic salt that acts as a catalyst to convert orthohydrogen into parahydrogen. 

The conversion process takes less than 12 hours for an efficiency of 98% conversion. 

If your experiment requires the use of parahydrogen, contact the instrument scientists.
